Some people need more sleep than others, some are night owls while others are early birds, and some are more sensitive to noise. To know how to sleep better, you need to know more about yourself.

SleepCoacher was designed to be your own personal sleep coach: it shows you a list of sleep expert-approved suggestions that you can incorporate into your life and see if they help you sleep better.

When you put your phone on the bed, the app monitors movement and noise while you sleep. When you wake up, it sends your sleep data to a system that reviews your sleep history, and learns how your behavior and sleep quality are related.

Since everyone responds to changes differently, SleepCoacher observes the outcomes of behavioral changes, and tells you what works best for you specifically. After a few nights of tracking your sleep and following the instructions of what to do, SleepCoacher lets you know which condition is more likely to help you sleep better (e.g. there is an 83% likelihood that wearing roomier PJs is helping you fall asleep faster).

The 10-Year Study on Sleep

To learn what behaviors affect your sleep quality, a week is not enough. Even a month can only tell you one or two things about your habits.
SleepCoacher will run for 10 years, so you as a user can optimize your sleep behaviors over a long series of mini-experiments. Start and stop each self-experiment whenever you please.
